SASH FASTENER AN D HOLDER.

SPECIFICATION formingpart of Letters Patent No. 255,282, dated March 21,1882.

Application filed December 10, 1881. (ModeL) To all whom it may concern:

Be it known that I, HARRY GREENFIELD, of Harrison, in the county ofHudson and State of New Jersey, have invented a new and usefulImprovement in Sash Locks and Holders, of which the following is afnll,'clear, and exact description.

This invention seeks to provide an automatic window-sash lock and holderor support having such construction and operation that it will not benecessary tolrold hack the latch with one hand while raising andlowering the sash.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is an elevation, partly in section, of a window-frame having myimproved lock and holder applied thereto. Fig. 2 is a sectionalelevation of the same, taken on the line 00 w of Fig. 1. Fig. 3 is aside elevation of a housing for the latch, and Fig. 4 is a frontelevation of the same.

Arepresentsthelocking-catch. B represents the holding-catch; and (Jrepresents the holders, of which there may be one, two, or more securedto the frame D of the window, as shown in the drawings, for holding thewindow at different heights. p The locking-catch A is formed with thecamprojection a, and is loosely pivoted to the plate b, which plate isformed with the lug e, which is recessed for holding the catch A, asshown in Fig. 2, and this plate is adapted to be securedv to the frameD, as shown, by screws, nails, or similar means.

The holder 0 is formed with the detent c and with the overhanging cam ordeflector d, and

A and catch under it, and thus lock the window, and when the sash israised will enter or drop into the detent c of the holder 0, and thushold or support the window.

To unlock the window for raising, it is only necessary to swing thelocking-catch A outward, which will permit the holdingcatch B to dropbehind it, which will hold the catch A so that its projection to willnot engage with the nose of the holding-catch, but will leave the sashentirely free to be raised, to be held by the supports or holders 0, aswill be readily understood.

In lowering the window the cam or deflector d of the holder G serves tothrow or swing the catch B back on its pivot, so that it will pass thedetent 0, unless the window be lowered slowly, when it will drop intothe detent, and thus support the window. When the hiusing F (shown inFigs. 3 and 4) is used the catch B will be pivoted to the inside of thehousing, and plate 9 will not be used.

In some cases the lower outer corner of the housing F will be formedwith the finger-lift f, and the plate 9 may have the lug or projectionj, which serves both as a finger-lift and as a stop to prevent the catch0 being thrown too far back by the cam or deflector d.

I do not confine myself to the use of my invention upon window-sash, asit may be used upon vertically-sliding windowfblinds and in otherplaces.

Having thus desci ibed my invention, I claim as new and desire to secureby Letters Patent- 1. The loosely-pivoted holding-catch B, incombination with the pivoted locking-catch A, formed with thecam-projection a, substantially as and for the purposes set forth.

2. The plate 0, formed with the recessed lug e, in combination with thepivoted lockingcatch A and the loosely-pivoted holding-catch B,substantially as and for the purposes set forth.

HARRY GREENFIELD.
